An XSS vulnerability exists in the login component of Zimbra Web Client, in which an attacker can execute arbitrary JavaScript by adding executable JavaScript to the loginErrorCode parameter of the login url.
Does this matter?
Lower severity and a low EPSS score (3.28%). Track it; it rarely justifies an emergency change on its own.
